Description
BACKGROUND OF THE INVENTION

The present invention is about the tool for meals in which the function of scissors is added to a fork or a spoon for meals. Although knife, fork and spoon are used as tools for meals in Western countries, chopsticks are mainly used in the East. Both hands must be used at meals with knife and fork. As good skill is necessary for us to use chopsticks, the development of more simple tools for meals has been desired. According to the Japanese utility model publication No. 39175-1974 about the tool for meals with the function of fork and chopsticks, the tool has no function of cutting foods into small pieces.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a fork or a spoon with the function of scissors. The fork with the function of scissors will be explained as follows. The fork has the function of scissors with two blade bodies. Each blade body consists of the tip, the central and the handle portions. In the tip portion a fork is set diverging and separating from the back portion and in parallel with it in the back portion of one edge in two edges in the tip of said scissors. Two blade bodies form scissors combined by pin at the axis of scissors in each central portion of said two blade bodies. As each edge of said two-blade bodies overlaps the other, the tip portion is similar to the tip of a usual fork for meals. The spoon with the function of scissors will be explained as follows. The spoon has the function of scissors with two blade bodies. Each blade body has the shape of one part in which the sunken portion of the tip of a usual spoon for meals is divided in two portions. Each blade body consists of the tip portion in which an edge is set in said divided border side, the central portion and the handle portion. Two blade bodies form scissors combined by pin at the axis of scissors in each central portion of said two blade bodies. As each edge of said two-blade bodies overlaps the other, the tip portion is similar to the sunken portion of a usual spoon for meals. These and further object and advantage of this invention will become apparent from following more detailed description of an illustrative embodiment of the invention, which will now be given in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention will now be described in greater detail with reference to the illustrated embodiment.

The fork with the function of scissors will be explained about Example 1 by referring to FIGS. 1 through 5. 1a and 1b are the edges forming scissors and they curve as shown in FIG. 2. 2a and 2b are the back portions equivalent to the edges 1a and 1b. 3a 3b are the curving forks such as the edges 1a and 1b as shown in FIG. 2, diverging and separating from said back portions 2a and 2b, being set in parallel with the same back portions. The tip portion of the present tool consists of the edges 1a and 1b and the forks 3a and 3b. The edges 1a and 1b are similar to the united fork wherein two edges of scissors 1a and 1b are overlapped. This tip portion is similar to that of a usual fork for meals. 4a and 4b are the central portions wherein the axis of scissors 7 is fixed. 5a and 5b are the handle portions of scissors. Edge 1a, backportion 2a, fork 3a, central portion of scissors 4a and handle portion 5a form one blade body 6a. The other edge 1b, back portion 2b, fork 3b, central portion 4b and handle portion 5b from the other blade body 6b. As a result of pin-combination of the blade bodies 6a and 6b at the axis of scissors 7 in the central portions 4a and 4b, a system of scissors is formed. The formentioned scissor type of device is capable of one hand use for medical or kitchen application.

In this tool for meals as illustrated in the side view of FIG. 2 the blade bodies 6a and 6b form a loose curve of letter S as a whole, curving against the plane central portions 4a 4b. Moreover in the blade bodies 6a and 6b the edge 1a and 1b overlap and the handle portions 5a and 5b do so because of the difference in turning plane at the axis 7. Consequently as illustrated in a plan view of FIG. 4 the present tool can be made the smallest on being stowed. As illustrated in FIG. 5, when the edge 1a crossing over the edge 1b, the sharp edges are fixed in the shoulder portions of the fork 3as and 3bs and in the central portions 4ac and 4bc around said shoulder portions, the solid foods such as crab's feet can be cut off easily if they are put in the space surrounded by said portions 3as, 3bs, 4ac and 4bc. As illustrated in FIG. 6 the tool for meals of Example 2 in which the forks 3a and 3b diverge two by two from each backportion 2a and 2b of two edges although the forks diverge one by one in Example 1.

As illustrated in FIG. 7 the tool for meals of Example 3 in which one fork diverges from the back portion of one edge in two edges and plural forks diverge from the back portion of the other edge. As illustrated in FIG. 8 the tool for meals of Example 4 in which one or plural forks diverge from the back portion of only one edge in two edges.

As illustrated in FIG. 9 the tool for meals of Example 5 in which the fork 3d fixed in the back portion of one edge can be fastened or unfastened freely in and from the back portion. FIG. 10 is a sectional view taken along lines X--X of FIG. 9. In FIGS. 9 and 10 a slender slit set in the root of the fork 3d is fixed in the projection 8 set vertically in the back portion 2a whose head similar to a plate. Then the fork 3d is fixed in the back portion 2a by making the fork 3d slide to the direction of the axis 7 of scissors.

As illustrated in FIG. 11 the tool for meals of Example 6 in which the forks 3e and 3f can be fastened or unfastened freely in and from the back portion. FIG. 12 is a sectional view taken along lines XII--XII of FIG. 11. In FIGS. 11 and 12 the fork 3e and 3f are fixed in each back portion 1b and 1a by the screw 10. As illustrated in the side view of FIG. 2 the tool for meals of Example 7 in which the edge, the fork and the handle portion bend backward against the central portion of scissors 4a and form a loose curve of letter S as a whole. The number and arrangement of fork can be selected in various ways as described in the previous paragraphs. As illustrated in the side view of FIG. 13 the tool for meals of Example 8 in which the edge and the forks 1a, 1b, 3a and 3b curve and the handle portion 5a and 5b form almost a straight line against the central portion of scissors 4a from the side view. The number and arrangement of fork can be selected in various ways as described previously. As illustrated in the side view of FIG. 14 in the tool for meals of Example 9 the edge and the forks 1a, 1b, 3a and 3b form almost a straight line and the handle portions 5a and 5b curve against the central portion of scissors 4a from the side view. The number and arrangement of fork can be selected in various ways as described in preceding paragraphs. As illustrated in the side view of FIG. 15 in the tool for meals of Example 10 the edge, the fork and the handle portion curve against the central portion of scissors from the side view. Each one is only in one side of the plane which involves the central portion of scissors. The number and arrangement of fork can be selected in various ways as described previously. The spoon with the function of scissors will be explained about Example 11 by referring to FIGS. 16 through 19. 11 is the tip portion similar to one side of the sunken portion in the tip of the usual spoon for meals divided in two longitudinally. The edge of scissors 12 is put on in said divided border side. One blade body 13a is composed of said tip portion 11, the central portion of scissors 4 and the handle portion 5. The other blade body 13b has also the tip portion with an edge, the central portion and the handle portion. The blade bodies 13a and 13b are combined by pin at the axis of scissors 7 in the central portion 4 of each blade body and form a pair of scissors. As illustrated in FIG. 16 when two edges 12 overlap each other, the tip portion 11 becomes similar to the sunken portion of the tip of the spoon for meals. As illustrated in FIG. 19 when two edges 12 are opened, there can be seen one of the objects of the present invention, which is the function of scissors. Two blade bodies 13a and 13b are combined by pin at the axis 7. This combination can be also one-touched method applied to the scissors for medical anatomization and for kitchen works. As illustrated in the sectional view of FIG. 18 the projection 14 is set in the outside bottom of the tip portion 11 as a stopper of an interlocking last point in the edge of scissors 12. This projection 14 stops the leak of liquid in the spoon in contact with the edge 12. If said projection 14 by heat-resisting and synthetic resin is fixed in the position of said outside bottom in order to stop the injury of the edge 12 by the strong pressure between the edge 12 stopping the leak and the projection 14, said leak and the injury of the edge 12 can be stopped.

As illustrated in the side view of FIG. 17 in this tool for meals the edge 12 of the tip portion 11 and the handle portion 5 curve against the flat central portion 4 and form a loose curve of letter S as a whole.

The tool for meals of Example 12 is as shown in FIG. 20. The original form of the tool for meals in the present example is used for meals of school boys and girls or for removing the seeds of watermelon. The tool for meals of the present example is an object wherein said original "spoon with divided tip" was improved according to Example 11. Because of narrow cuts 15 from the extreme end of the tip portion 11 toward the hands even if this tool is mainly used as a spoon with both tip portions closed, there is also the function of fork similar to the original "spoon with divided tip". Further as this tool for meals is used with tip portions being opened to some degree, it is convenient that both functions of fork and scissors can be seen and used. The tool for meals of Example 13 is as shown in FIG. 21. In the tool for meals of the present example, on dividing the sunken portion of the tip of the spoon longitudinally, it is not divided in the same shape and the tip portion 11 of the bigger portion is used as a spoon. The small portion 16 is similar to a thick sickle with an edge. The said spoon serves the function of holding food cut by movement of small portion 16. The function of scissors is the same as in other examples.

In examples 11 through 13 the relation among the tip, the central and the handle portion is not limited to a loose curve of letter S as shown in the side view of FIG. 17. As illustrated in the side view of FIG. 23 and 24 it is possible to make the handle portion 5 almost straight-lined or make it almost vertical in opposite direction against FIG. 17 on use. The shapes of said various handle portions can be decided according to the desires of the persons who use the present tool for meals.

The examples for use of the present tool for meals will be explained according to the kinds of foods.

(a) In case of boiled rice, either the fork or the spoon with the function of scissors of the present invention can be used with convenience.

(b) In case of juicy dishes, the big foods in juice are cut in right size in cup and can be eaten easily. It is convenient especially for elder people to cut foods in small pieces and eat them easily with the present tool at any time.

(c) In case of dishes, this tool is useful to stab, pinch and spoon dishes. For example, a cutlet, a beef steak and a fillet can be cut just as they are in plates without knife and fork. Any food can be carried to the user's mouth, being cut in small pieces according to their situations.

(d) Bean curds and boiled beans can be spooned by the tip portion of this tool in the same way as in a usual spoon or fork.

(e) In case of noodles and spaghetti, when they are linking between dish and mouth, they can be cut easily at any length by this tool for meals.

(f) Oranges can be easily peeled being cut in cross at the middle part of the skin by the tip of edge. The fruit bags of oranges can be eaten easily with a cut by the scissors.

(g) In addition to these examples for use the present tool for meals is also effective in other various cases like paring the skin of sausages and cutting off a shell ligament from its shell in cups and so forth.

As above mentioned, the tool for meals of the present invention makes it possible to cut, stab, pinch or spoon foods by only itself, and its handling can be easily done by only one hand. Five functions of chopsticks, knife, spoon, fork and scissors in Examples 11 through 13 are involved sufficiently in the present tool. Because of its handy shape, it is suitable not only for the meals in common homes, office restaurants, trains planes and school lunch feeding, but also for the meals in trip, hiking and calamity countermeasure. The present tool is also fitting for the meals of elder people and the handicapped.
